          摘   要  目的  评估瑞派替尼与舒尼替尼作为晚期胃肠道间质瘤(GIST)患者二线治疗方案的经济性。方法  基于INTRIGUE研
          究数据构建动态Markov模型,设定模型循环周期为6周,模拟患者15年的直接医疗成本和质量调整生命年(QALYs),以增量成
          本-效果比(ICER)为评价指标,比较ICER与意愿支付(WTP)阈值(我国2023年的3倍人均国内生产总值,268 200元/QALY)的大
          小;并对模型输出结果进行单因素敏感性分析和概率敏感性分析以考察模型的稳定性。结果  瑞派替尼方案的健康获益低于舒尼
          替尼(1.21 QALYs vs.1.31 QALYs),但成本更高(323 401.88元 vs. 227 532.40元),为绝对劣势方案。单因素敏感性分析结果表明,
          瑞派替尼和舒尼替尼费用、无进展生存状态的效用值对ICER影响较大。概率敏感性分析提示研究结果较稳定,且随着WTP增
          加,瑞派替尼方案具有经济性的概率始终远低于舒尼替尼,并呈下降趋势。结论  在当前我国的经济背景下,与舒尼替尼相比,瑞
          派替尼作为晚期GIST的二线治疗方案并不具有经济性。

          Cost-effectiveness  of  second-line  treatment  of  advanced  gastrointestinal  stromal  tumors  with  ripretinib
          versus sunitinib

          ABSTRACT    OBJECTIVE  To  evaluate  the  cost-effectiveness  of  ripretinib  versus  sunitinib  as  a  second-line  treatment  option  for
          patients  with  advanced  gastrointestinal  stromal  tumors (GIST).  METHODS  Based  on  the  data  of  INTRIGUE  study,  a  dynamic
          Markov model was constructed, with a cycle of 6 weeks; this model was used to simulate patients’ direct medical costs and quality-
          adjusted  life  years (QALYs)  over  15  years.  Using  the  incremental  cost-effectiveness  ratio (ICER)  as  the  evaluation  metric,  a
          comparison  was  made  between  the  ICER  and  the  willingness-to-pay (WTP)  threshold (3  times  the  per  capita  gross  domestic
          product,  which  amounts  to  268  200  yuan/QALY).  One-way  sensitivity  analyses  and  probabilistic  sensitivity  analyses  were
          performed on the model outputs to examine the stability of the model. RESULTS The health benefits of ripretinib were lower than
          those of sunitinib (1.21 QALYs vs. 1.31 QALYs). Still, the costs were higher (323 401.88 yuan vs. 227 532.40 yuan), making it
          an inferior regimen. The results of the one-way sensitivity analysis suggested that the cost of ripretinib and sunitinib, and the health
          utility  value  in  progression-free  survival  status  had  a  greater  impact  on  the  ICER  of  the  model.  Probabilistic  sensitivity  analysis
          suggested  that  the  results  of  the  study  were  stable,  and  the  probability  of  the  cost-effectiveness  advantage  of  ripretinib  was  always
          much  lower  than  that  of  sunitinib  with  the  increase  of  WTP  threshold,  and  showed  a  decreasing  trend.  CONCLUSIONS  In  the
          current economic context of China, ripretinib does not have a cost-effectiveness advantage over sunitinib as a second-line treatment
          for advanced GIST.
